This conventional structure will be explained with reference to FIG. was rotatably fitted onto the outside, and a retaining plate 020 was fixed to the pivot shaft 11 with bolts 021 to prevent the mounting base 8 from being pulled out.

In this way, in a structure that uses a cylindrical handle mount 8 that fits around the pivot shaft 11 on the mounting table 6, the plowing depth can be determined by rocking the machine back and forth around the grounding point of the wheels. In order to easily transmit the operating force such as pushing down or pulling up the handle during work such as changing the handle, the length of the engagement between the pivot shaft 11 and the handle mounting base 8 is increased to some extent to increase the contact area. However, if the mating length is increased in this way, the height of the upper part of the aircraft above the ground becomes high, which has the disadvantage that it is difficult to use when working by passing through low fruit trees. .

The characteristic configuration of the present invention to achieve the above object is that a handle mounting base is attached to a mounting base fixed to the traveling machine body so as to be rotatable around the vertical axis.
In this walk-behind mobile agricultural machine in which the handle is attached to the handle mounting base, the facing surfaces of the mounting base and the handle mounting base are each formed into wide flat surfaces, and the central part of the facing surfaces of the two bases is A large-diameter pivot shaft having the above-mentioned vertical axis is protruded from either the mounting base or the handle mounting base, and a circular hole into which the pivot shaft is inserted is formed in the other, and from this circular hole. A stopper for restricting the pivot shaft from coming out of the circular hole is attached to the protruding free end of the pivot shaft, and further, the handle is separated radially outward from the pivot shaft. One end side is pivotally connected to the handle mounting base at the position, and at a position opposite to the position where the handle is pivotally connected to the handle mounting base across the pivot shaft, the above-mentioned A locking mechanism is provided for fixing the handle mounting base to the mounting base in a non-rotating state, and this configuration provides the following functions and effects.

The mounting structure of the handle, which is rotatable around the vertical axis, is not composed of an axially long pivot shaft and a long cylindrical body that fits onto the shaft, but is mounted on the top surface of a flat and wide mounting table. Similarly, flat and wide handle mounting bases are provided facing each other, and the wide flat surfaces are in contact with each other so that operating force such as pushing down or pulling up the handle can be transmitted to the traveling aircraft side.

付台上に長い枢支軸やハンドル連設用の長い筒状
体を立設する必要がない。 Therefore, the pivot shaft only needs to have the role of regulating horizontal positional deviation between flat surfaces, and there is no need for receiving the operating force or for mounting for connecting the handle. There is no need to erect a long pivot shaft or a long cylindrical body for connecting the handle on the handle mounting base.

Because of the above effects, there is no large protrusion such as a long pivot on the handle mounting base, which makes it easy to install the handle as low as possible, making it bulky from the ground, suitable for work between low fruit trees, etc. There is an advantage that it is easy to obtain a low walking type mobile agricultural machine.
